All results in the latest version of the spreadsheet were measured on Indiana University Data Capacitor OSS nodes, so if Bret or Steve from IU are following this thread, they can likely provide more details. I don't recall the exact CPU used in these nodes. They are Intel Woodcrest-based servers from Dell. The OS is RHEL 4 and storage is connected via 4 GBit FC.
